I'd guess it's a gremlin. :-)

I'm always wary of using a repeat loop that waits for an event. I'm  
never sure what should happen to events that would normally get fired  
before the event that's being waited for. (mouseleave, etc) So there's  
some uncertainty (in my mind at least) of what the current "target" is.

The following script, whether placed in the field's script or the  
card's script seems to behave as you would expect.

local sTracking = false

on mouseUp
   put not sTracking into sTracking
end mouseUp

on mouseMove
    if sTracking then
       put the mouseLine
    end if
end mouseMove
